Description

Internal mixer pressing device

technical field

The utility model relates to a pressing device of a banbury mixer.

Background technique

The internal mixer is widely used in the rubber industry, and it is the key equipment of the tire manufacturing plant. The pressing device is installed above the feeding device of the internal mixer. Apply a certain pressure to the material. As the internal mixer is more and more widely used in the rubber industry at home and abroad, the requirements for the equipment of the internal mixer are getting higher and higher, and the pressing device of the internal mixer is required to run more smoothly. , which runs faster.

Utility model content

The purpose of the utility model is to provide an energy-saving, stable operation and fast operation speed pressing device of the internal mixer.

The technical solution adopted by the utility model to achieve the above purpose is: a pressing device of an internal mixer, including a support frame (2), an oil cylinder (3), a pressing seat plate (4) and a pressure weight (5). The support frame (2) is fixed on the body of the internal mixer through the pressing seat plate (4), the weight (5) is fixed on the cylinder body of the oil cylinder (3), and the end of the piston rod of the oil cylinder (3) is fixed on the support on the shelf (2).

The end of the piston rod of the oil cylinder (3) is fixed on the support frame (2) through the fixing nut (1).

A guide hole is provided on the pressing seat plate (4).

The utility model is a pressing device of an internal mixer. The oil cylinder is placed in the center of the whole device, and the rigidity of the cylinder body is far better than that of the piston rod. In the past, the problem of micro-deformation of the piston rod under the force of the traditional structure can effectively ensure that the up and down of the weight is more stable, so the force of the weight in this structure is more uniform and reasonable. When the weight goes down, it exerts pressure on the material When the oil cylinder enters the rodless cavity, the hydraulic oil has a larger action area, and a smaller oil pressure can be used to obtain a larger applied force. Under the condition of applying the same pressure to the material, the hydraulic pressure provided by the hydraulic oil pressure The motor power requirements of the station oil pump can be smaller, so as to achieve energy saving. When the weight goes up, the rod chamber of the oil cylinder enters the oil, and the hydraulic oil has a small action area. Under the same flow conditions, a faster upward speed can be obtained ; The structure is simple, compared with the traditional structure of the pressing device of the internal mixer, this structure has no guide rod, and only one oil cylinder works, which not only saves two guide rods in the traditional structure, but also saves one pressing material Oil cylinder, but its working performance is not only not reduced, but also improved, which can make the upward and downward movement of the weight more stable, the running speed is faster and more stable, and the energy consumption is reduced.

detailed description

As shown in Figure 1, the pressing device of the internal mixer includes a support frame 2, an oil cylinder 3, a pressing seat plate 4 and a weight 5. The weight 5 is fixed on the cylinder body 3, and the piston rod of the oil cylinder 3 passes through the fixing nut 1 It is fixed on the support frame 2, and the support frame 2 is fixed on the body of the internal mixer through the pressing seat plate 4. When the pressure weight 5 descends and pressurizes, the rodless chamber of the oil cylinder 3 enters the oil, and the hydraulic oil has a larger action area. Smaller oil pressure can be used to obtain greater force. When the weight goes up, the rod cavity of oil cylinder 3 enters the oil, and the hydraulic oil has a smaller action area, so that a faster upward movement can be obtained with a smaller hydraulic oil flow rate. Speed, the pressing device of the internal mixer of the utility model drives the oil cylinder right above the feeding device of the internal mixer, the piston rod of the oil cylinder is fixed on the support frame through the fixing nut, and the cylinder body of the oil cylinder drives the weight fixed on it to move up and down . The support frame is fixed on the body of the internal mixer through the pressing seat plate; the driving cylinder is arranged in the middle of the whole device, the piston rod and the fixed support are fixedly connected, and there is a guiding function between the cylinder body and the piston rod, and the piston and the cylinder There is a guiding effect between the cylinder body, and there is also a guiding effect between the oil cylinder body and the fixed support. During the whole process of the weight going up and down, there are related parts to play a guiding role, and the weight runs more smoothly; when the weight is down and pressurized, the rodless chamber of the oil cylinder enters the oil, and the hydraulic oil has a larger action area , a larger force can be obtained with a smaller oil pressure; when the weight is moving upward, the rod chamber of the oil cylinder enters the oil, and the hydraulic oil has a smaller action area. Under the same flow rate, a faster lifting can be obtained speed.
